Taxis with and without passengers, 2010
"Blue is where taxis are carrying passengers. Red is where passenger seats are empty. Check out the Bay Bridge approach east of 5th Street - eastbound they are always carrying passengers to the East Bay, westbound they are always empty (presumably because passenger trips the other way are handled by Oakland taxis). Something similar also happens on the Golden Gate Bridge and on the Southern Freeway." - Eric Fischer
